Description

TECHNICAL FIELD
The present invention relates to an air conditioner that conveys humidified air to an indoor unit and regulates the humidity of the air inside a room by means of a humidification unit disposed in an outdoor unit.
BACKGROUND ART
In a separate type of air conditioner, an outdoor heat exchanger disposed inside an outdoor unit is connected to an indoor heat exchanger disposed in an indoor unit via refrigerant lines, and each heat exchanger is constructed so that they conduct cooling and heating operations by functioning as a refrigerant condenser and evaporator.
An outdoor fan that serves to generate air flow is disposed inside the outdoor unit. This outdoor fan introduces outside air into the outdoor unit, which allows heat exchange to occur between the refrigerant that flows through that interior of the outdoor heat exchanger and the air.
At the same time, an indoor fan is disposed in the indoor unit and serves to generate air flow inside the indoor unit casing. This indoor fan unit draws in indoor air, which allows heat exchange to occur between the refrigerant the flows through the interior of the indoor heat exchanger and the air.
Generally speaking, there are times when the indoor relative humidity will drastically decrease during heating operations, due to the fact that there is no supply of moisture while the indoor air temperature rises. Because of this, a humidifying unit has been proposed that is disposed in the air conditioner and supplies humidified to the room. For example, the humidifying unit is composed of a disk shaped rotor rotatably supported thereon, which is formed from a porous moisture absorbing material such as zeolite and the like that adsorbs moisture from the air, and desorbs the adsorbed moisture by means of heating. The humidifying unit includes a moisture absorption fan that introduces outside air and generates air flow through a part of the rotor in order to allow the rotor to adsorb moisture from the air, and a humidifying fan that generates air flow in order to convey humidified air containing moisture desorbed from the rotor to the indoor unit. The air flow from the moisture absorption fan and the air flow from the humidifying fan are structured such that they each flow through the rotor, and the rotational positions of each flow through the rotor are different from each other. In addition, a heater that heats the rotor is disposed at the point where the air flow from the humidifying fan flows through therethrough.
The moisture contained in the air flow from the moisture absorption fan is adsorbed by the adsorbent material in the rotor. The rotor is driven by a motor, the moisture is desorbed from the rotor at the point in which it is heated by the heater, and the moisture from the humidifying heater can be supplied to the air flow.
The humidifying unit described above is either installed on or nearby the outdoor unit, adsorbs the moisture from the air taken in from the outside by the moisture absorption fan, and again removes the adsorbed moisture and conveys it to the indoor unit as humidified air.
After heat exchange takes place between the indoor air drawn into the indoor unit and the indoor heat exchanger, the indoor fan is driven in order to generate air flow for ventilating the indoor space. The indoor heat exchanger is composed of a plurality of planar cooling fins arranged parallel to one another on a heat transfer line that curves back and forth from left to right. When the air flow generated by the indoor fan flows through the spaces between the cooling fins, heat exchange occurs with the refrigerant inside the indoor heat exchanger.
When a humidified air discharge port is arranged such that the humidified air supplied from the humidifying unit flows across the cooling fins of the heat exchanger, wind noise is generated by the cooling fins, and thus noise is generated by the indoor unit.
It is an object of the present invention to devise an air conditioner having a humidifying unit in which noise generation is suppressed during operation.

    A propeller fan 29 that discharges air outside after heat exchange with the outdoor heat exchanger 24 is provided in the outdoor air conditioning unit 5. The propeller fan 29 is driven by a fan motor 30.
    [Humidifying unit]
    The structure of the humidifying unit 4 will be described based upon the exploded perspective view of Fig. 3.
    The humidifying unit 4 is comprised of a humidifying unit casing 48 that is positioned on the upper portion of the outdoor unit 3. A humidifying rotor 58 is disposed inside the humidifying unit casing 48. As noted previously, the humidifying rotor 58 adsorbs moisture from the air that it comes in contact with, and is composed of a porous, disk shaped zeolite that has the ability to desorb the adsorbed moisture by heating. The humidifying rotor 58 is rotatably supported on a support shaft 59 provided on the humidifying unit casing 48 via a rotor guide 60. Gear teeth are formed on the circumferential surface of the humidifying rotor 58, which engage with a rotor drive gear 62 that is installed on a drive shaft on a rotor drive motor 61.
    A heater assembly 64 is disposed on the upper surface of the humidifying rotor 58 such that it covers approximately half thereof. The heater assembly 64 is composed of a heating element 66, an upper cover 65 that covers the heating element 66, and a lower cover 69 that includes an intake port 67 for air intake and a discharge port 68 that discharges air that has been heated by the heating element 66. The heater assembly 64 is installed above the humidifying rotor 58 via a heater connection plate 63.
    A humidifying fan 70 is disposed below the humidifying rotor 58 in a position facing the heating assembly 64. The humidifying fan 70 is a centrifugal fan that is disposed inside the casing and connected to a humidifying side connection duct 72, and is integral with a humidifying fan inlet 71 that is installed below the humidifying rotor 58. The humidifying fan 70 discharges air that has flowed through the humidifying rotor 58 into the connection duct 72, and sends humidified air to the indoor unit 2 via a humidifying hose 73 and the humidified air line 7.
    An adsorption side connection duct 74 is provided on the upper surface of the humidifying rotor 58 such that it covers the portion thereof not covered by the heater assembly 64. The adsorption side connection duct 74 forms an air flow route that runs from below the humidifying rotor 58, through the humidifying rotor 58, and ends in a adsorption fan container 75 that is adjacent to the container for the humidifying rotor 58.
    A bell mouth 84 that includes a port 85 that connects to the air flow route formed by the adsorption duct 74 is provided above the adsorption fan container 75. An adsorption fan 81 is contained in the adsorption fan container 75 and is freely rotatable therein. The adsorption fan 81 is a centrifugal fan that is structured so as to take in air from the adsorption side of the bell mouth 84, and discharge this air toward the rear of the adsorption fan container 75.
    The adsorption fan 81 is driven by an adsorption fan motor 83. The adsorption fan motor 83 is fixed inside the humidifying unit casing 48 by means of a motor mount 82.
    In this type of humidifying unit 4, an air flow is generated by driving the adsorption fan 81, in which air is taken in from the outside, passes through a portion of the humidifying rotor 58, and is discharged to the rear via the adsorption connecting duct and the adsorption fan 81. When the air taken in from the outside passes through the humidifying rotor 58, the humidifying rotor 58 adsorbs moisture contained therein.
    In addition, an air flow is generated by driving the humidifying fan 70, in which air is taken in from the outside, passes through the humidifying rotor 58 from the lower part to the upper part thereof, is introduced into the upper cover 65 from the lower cover 69 of the intake port 67, is discharged from the discharge port 68 and passed through the humidifying rotor 58 a second time from the upper part to the lower part thereof, and is discharged to the humidifying side connecting duct 72. When this occurs, the air flow introduced from the outside comes into contact with the heating element 66 disposed inside the upper cover 65 of the heater assembly 64 and is heated. Thus, moisture adsorbed in the humidifying rotor 58 can be desorbed and supplied to the indoor unit 2 as humidified air by means of the air flow generated by the humidifying fan 70.
    [Indoor air conditioning unit]
    An exploded, perspective view of the indoor unit 2 is shown in Fig. 4.
    In Fig. 4, the indoor unit 2 includes a front grill assembly 101, and a front panel 102 that is mounted on the front of the front grill assembly 101. The front grill assembly 101 is comprised of an upper intake port 103 that is formed from a number of slit-shaped openings on the upper surface thereof. In addition, the front panel 102 is formed from a front intake port 104 that is open on the upper portion and side portions thereof.
    Air filters 105 are interposed between the upper intake port 103 of the front grill assembly 101 and the front intake port 104 of the front panel 102, and serve to clean the air.
    The front grill assembly 101 is installed on a base frame assembly 106 that is positioned on the rear thereof, and is configured to be a casing that contains the internal parts of the indoor unit 2. The casing composed of the front grill assembly 102 and the base frame assembly 106 is latched onto an installation plate 107 that is fixed onto an indoor wall, and thereby installed indoors.
    A fan container 109 that stores the cross flow fan 12 is provided in the base frame assembly 106. The cross flow fan 12 is installed such that it is freely rotatable via a bearing member 110, and the indoor fan motor 13 is provided on the side of the cross flow fan 12 opposite the bearing member 110. A side plate 111 is installed on the outer side of the indoor fan motor 13.
    The indoor heat exchanger 11 is installed such that it surrounds the cross flow fan 12 on the front, top and upper rear portion thereof. The indoor heat exchanger 11 includes a large number of cooling fins installed on a heat transfer line that has a plurality of curved portions on both ends thereof in the lengthwise direction. Air that has been taken in from the upper intake port 103 and the front intake port 104 by operation of the cross flow fan 12 passes through the cross flow fan 12 and exchanges heat with the refrigerant that flows inside the heat transfer line. The indoor heat exchanger 11 is connected to the refrigerant line from the outdoor unit 3 via a refrigerant line 108 that extends from the indoor heat exchanger 11.
    A drain pan 112 for receiving condensed water produced during heat exchange is provided on the lower part of the indoor heat exchanger 11. A drain hose 113 for discharging condensed water to the outside is installed on the drain pan 112. During cooling operations, moisture in the air that comes into contact with the indoor heat exchanger 11 condenses and drips downward because the indoor heat exchanger 11 acts as an evaporator. The drain pan 112 is constructed to receive the condensed water produced thereby, and drain it off via the drain hose 113.
    An electrical equipment box 114 that contains a printed circuit board that includes a control circuit and the like thereon, and an electrical equipment cover 115 that covers the front of the electrical equipment box 114, are provided on the lower front portion of the front grill assembly 101. In addition, a discharge port for the air flow that is generated by the cross flow fan 12 is provided on the lower portion of the electrical equipment box 114. Horizontal blades 116, 116, and a plurality of vertical blades 117, 117 that are connected to vertical blade connecting rods 118, are pivotably disposed on the discharge port. The horizontal blades 116, 116 are constructed such that they can be pivoted up and down by a horizontal blade operation motor 119, and the vertical blades 117, 117 are constructed such that they can be pivoted from left to right by a vertical blade operation motor 120.
    A duct assembly 171 is installed on one side of the base frame assembly 106. The duct assembly 171 is comprised of a humidifying hose connector 172 positioned on the bottom thereof, a duct formation 173 positioned in the middle thereof, and a humidified air discharge port 174 that is positioned on the upper portion thereof. The humidified air line 7 (shown in Fig. 1) is connected to the humidifying hose connector 172 of the duct assembly 171, and introduces humidified air supplied from the humidifying unit 4. The duct formation 173 positioned in the middle of the duct assembly 171 forms a space in which humidified air passes therethrough. Humidified air introduced from the humidifying hose connector 172 is conveyed to the end of the duct assembly 171, and is discharged into the air flow generated by the cross flow fan 12 from the humidified air discharge port 174.
    The humidified air discharge port 174 of the duct assembly 171 is disposed such that the humidified air is discharged parallel with respect to the cooling fins provided on the indoor heat exchanger 11, and generates a humidified air flow that is parallel to the air flow generated by the cross flow fan 12. Thus, the humidified air discharged from the humidified air discharge port 174 can be prevented from generating noise cause by the air flowing across the cooling fins of the indoor heat exchanger 11, thereby allowing a quite indoor unit 2 to be devised.
    [Humidified air discharge port]
    The disposition of the humidified air discharge port 174 will be described based upon Fig. 5.
  • (A) The humidified air discharge port 174 will be considered in a first position 181, in which it is disposed upstream of the air filters 105. Here, the humidified air discharge port 174 is disposed between the upper intake port 103 of the front grill assembly 101, the front intake port.104 of the front panel 102, and the air filters 105. Thus, the humidified air from the humidifying unit 4 can be mixed with the air taken in from the upper intake port 103 and the front intake port 104, and supplied to a room indoors.During the operation of the air conditioning unit, the air taken in from the upper inlet port 103 and the front inlet port 104 and mixed with the humidified air is brought into contact with the indoor heat exchanger 11, and heat is exchanged therewith. However, it is thought that there will not be very much moisture condensed from the air due to heat exchange with the indoor heat exchanger 11, because there are many times during the winter in Japan in which humidification operations will take place when the air is dry, and heating operations normally take place during this period.In addition, even when there is dust and other contaminants in the humidified air that is supplied from the humidifying unit 4, it can be prevented from entering indoors because it will be removed by the air filters 105.The indoor heat exchanger 11 is comprised of a plurality of planar cooling fins 177, and the heat transfer line (not shown in the figure) that curves left to right passes through heat transfer line through holes 178 in the cooling fins 177. From the humidified air discharge port 174 disposed in the first position 181, the humidified air will be discharged parallel with respect to the cooling fins 177, and thus the generation of operational noise can be suppressed.
  • (B) The humidified air discharge port 174 will be considered in a second position 182, in which it is disposed between the air filters 105 and the indoor heat exchanger 11.
    • Here, after air is taken in from the upper intake port 103 of the front grill assembly 101 and the front intake port 104 of the front panel 102, and is passed through the air filters 105, it will be mixed with the humidified air supplied from the humidifying unit 4 and blown indoors.
    Thus, moisture from the humidified air will not adhere to the air filters 105, and variation in the amount of humidity generated due to moisture adhering to the air filters 105 can be eliminated.
    In addition, like in the case of the humidified air discharge port 174 disposed in the first position 181, humidified air will be discharged from the humidified air discharge port 174 disposed in the second position 182 horizontally with respect to the cooling fins 177, and thus the generation of operational noise can be suppressed.

    With the air conditioner according to claim 2, moisture from the humidified air will not adhere to the air filters, and variation in the amount of humidity generated due to moisture adhering to the air filters can be eliminated.
    With the air conditioner according to claim 3, even when there is dust and other contaminants in the humidified air that is supplied from the humidifying unit, it can be prevented from entering indoors because it will be removed by the air filters.
